As if the flooding, downed trees, power outages and damaged homes and businesses weren't enough, Hurricane Isaac left behind another reminder of its brute force: large amounts of stinky, decaying marsh grass strewn about the northern shore of Lake Pontchartrain.

Who knows exactly how far the grass rode Isaac's surge before being deposited, but on the Mandeville lakefront it's hanging in trees, draped over benches, sticking through fences and blanketing some roadsides and neutral grounds. In some spots, it has already been pushed into large piles, waiting to be hauled off.
